R&D,Innovation and Knowledge Spillovers: A Reappraisal of Bottazzi and Peri (2007) in the Presence of Cross‐Sectional Dependence

Bottazzi and Peri (Economic Journal 2007; 117 : 486–511) show the existence of a cointegrating relationship between the domestic stock of knowledge, domestic R&D and the international knowledge stock for a panel of OECD countries and interpret it as evidence supporting the semi‐endogenous versus the endogenous growth theory. We replicate the baseline specification of their study and we show that main results are robust to the use of a different estimation strategy (Bai et al., Journal of Econometrics 2009; 149 : 82–99) that duly takes into account cross‐sectional correlation: interestingly, in this case we also find a larger role for knowledge spillovers.

In what sequence are information sources consulted by involved consumers? The case of automobile pre-purchase search

This study investigates the relationship between involvement and use of multiple information sources in the case of pre-purchase information search for automobiles. We consider the moderating role played by the sequence in which information sources are consulted. We explore our theoretical framework on a sample of 1261 Dutch consumers using a combination of structural equation modelling and cluster techniques. The results lend support for the claim that more involved consumers search more, and across more, information sources. We also identify clusters of consumers based on their search strategies, as defined by the sequencing of information sources used. Finally, research and managerial implications are discussed.     

Mortgage lending on Native American reservations: Does a guarantee matter?

The Section 184 Indian Home Loan Guarantee Program provides lenders with a 100 percent guarantee for mortgage loans to Native Americans residing on reservations belonging to tribes that have chosen to participate in the program. We find that Native Americans residing on trust land whose tribes have adopted Section 184 have a marginally statistically significantly higher loan approval rate than Native Americans residing on trust land whose tribes have not adopted Section 184. However, the statistical significance disappears once tribe fixed effects are included in the analysis, suggesting that underlying tribe characteristics correlated with the adoption of Section 184 are more important determinants of access to credit than is Section 184 per se.     

The Role of Fair Value Accounting in Promoting Government Accountability

A key factor to improve the financial accountability of governments is the existence of a set of generally accepted financial reporting of standards, such as IPSAS issued by the IFAC, which seek to enhance information transparency. This paper examines the capability of fair value accounting to improve, through financial transparency, government accountability, analysing the possible effect of the implementation of this measurement basis on understandability, comparability and timeliness—three qualitative characteristics linked to the relevance of financial reporting. This paper further considers whether the difficulties involved in achieving FV estimations could affect government financial accountability. The findings indicate that FVA implementation could enhance accountability by improving understandability, comparability and timeliness in governmental financial reporting, although the use of objective measures to estimate the FV of assets is fundamental. In addition, the type of assets and the existence of an active market are crucial to improving the comparability of financial statements under FVA, whereas improving timeliness could be limited by the possibility of estimating FV measures in‐house.     

The impact of recall periods on reported morbidity and health seeking behavior

Between 2000 and 2002, we followed 1621 individuals in Delhi, India using a combination of weekly and monthly-recall health questionnaires. In 2008, we augmented these data with another 8 weeks of surveys during which households were experimentally allocated to surveys with different recall periods in the second half of the survey. We show that the length of the recall period had a large impact on reported morbidity, doctor visits; time spent sick; whether at least one day of work/school was lost due to sickness and; the reported use of self-medication. The effects are more pronounced among the poor than the rich. In one example, differential recall effects across income groups reverse the sign of the gradient between doctor visits and per-capita expenditures such that the poor use health care providers more than the rich in the weekly recall surveys but less in monthly recall surveys. We hypothesize that illnesses – especially among the poor – are no longer perceived as “extraordinary events” but have become part of “normal” life. We discuss the implications of these results for health survey methodology, and the economic interpretation of sickness in poor populations.     

EURO CORPORATE BOND RISK FACTORS

This paper investigates the determinants of credit spread changes in euro‐denominated bonds. We adopt a factor model framework, inspired by the credit risk structural approach, as credit spread changes can be easily viewed as an excess return on corporate bonds over Treasury bonds. We try to assess the relative importance of market and idiosyncratic factors as an explanation of movements in credit spreads. We adopt a heterogeneous panel with a multifactor error model and propose a two‐step estimation procedure, which yields consistent estimates of unobserved factors. The analysis is carried out with a panel of monthly redemption yields on a set of corporate bonds for a time span of 3 years. Our results suggest that the euro corporate market is driven by observable and unobservable factors. The unobservable factors are identified through a consistent estimation of individual and common observable effects. The empirical results suggest that an unobserved common factor has a significant role in explaining the systematic changes in credit spreads. However, in contrast to evidence regarding US credit spread changes, it cannot be identified as a market factor. Copyright © 2011 John Wiley & Sons, Ltd.     

Determinants of the satisfaction of firms with the competencies of university students: a Spanish case study

Spanish universities pay little attention to business demands with regard to workforce training and to the research that has been developed in this area. The present study analyses the effect of various factors on firms’ satisfaction with the education provided by universities. The factors include the content of the student's major subject of study and social, methodological and participation skills. The data were obtained from a survey of businesses. Although the results obtained show that all of the factors have an impact on overall satisfaction, they are not of equal importance. University managers may be able to use the information obtained from this study as a basis for designing and implementing action that might improve employers’ level of satisfaction, which has considerable positive consequences. Moreover, the study's methodology could be applied to other outputs of universities, such as the research performed.     

Generalized cumulative residual entropy and record values

The Shannon entropy of a random variable has become a very useful tool in Probability Theory. In this paper we extend the concept of cumulative residual entropy introduced by Rao et al. (in IEEE Trans Inf Theory 50:1220–1228, 2004). The new concept called generalized cumulative residual entropy (GCRE) is related with the record values of a sequence of i.i.d. random variables and with the relevation transform. We also consider a dynamic GCRE obtained using the residual lifetime. For these concepts we obtain some characterization results, stochastic ordering and aging classes properties and some relationships with other entropy concepts.     

Employing the business model concept to support the adoption of product–service systems (PSS)

Although the existing literature indicates that the business model concept can be useful to implement product–service systems (PSS), there is still a paucity of guidelines to assist companies in this respect. Therefore, this paper proposes a framework to support the adoption of PSS employing the business model concept. This framework was developed based on literature review and intends to guide the company on the analysis of their business context, on the choice of the appropriate type of PSS and on the definition of their PSS characteristics. A single case study was then performed to illustrate an application of the framework in a machine tool manufacturer and provide research insights. Overall, results indicate that the framework can provide companies with a useful reference to PSS implementation, helping on the investigation of different PSS scenarios as well as the main barriers and challenges to be overcome.
